Awesome bikes thanks for the pics guys. I cant even imagine unleashing a 750 2 stroke, the load you'd have to be putting on that motor to get it to smooth out. I'd like to try for sure but I think the seat would be striped & wet after.

What gives it away as a T500 based TR replica? I know a little bit about Yamaha twins* but buggar all about much else.

This one is in Oz. And that was a correct statement in April, 2012.

*just enough to make an idiot of myself.

I'm assuming it's a TR500 Replica because of the overall stance of the bike, width of the rims, the fact that it is using the TR500 colors, etc. I could be wrong, and it could be a TR250 Rep, but the TR250s had really skinny tires. It might also be an authentic TR500, it's almost impossible for me to tell with my limited knowledge. If it is a replica, it is very well done, as the frame has been built to match the TR frame, which had wider spacing on the top tubes and no taper like the T500 frames.

Beautiful bike!

Fair enough. I suppose it's a moot point. Unless your going to buy it, it probably doesn't matter. No, I'll say it doesn't matter. If it keeps the owner happy, then that's enough. If it happens to be buike porn too, that's a bonus. A'd also suspect that, after this many years 'original' has to have the addendum 'specs'.

I wonder what other snaps I took of it? I want to use the same red on my RD project, whenigetaroundtuit.

My late brother bought this RD400f new back in 1979 and slowly turned it into a dedicated racer. It was last run at Willow sometime back in the late 80's and has been carted about the country in ever smaller boxes since.

After his passing last summer I decided it would be a nice tribute to put it back together again and get it back to the track. So far I have a dry assembled chassis and the engine is mostly together.... once I figure out what pistons to fit I can finish putting it back into one piece.

If anyone remembers seeing this bike in action I'd love to know about it.

TZ750A special, called "Monoca", with Harris monoshock conversion, TZ350 barrels, lots of other mods, and 152rwhp. This pic is at Phillip Island. My first race on it was in the wet at Pukekohe, 183mph - on wets, fortunately. The thing could fly, but it was a bastard in corners because the power delivery was crazy stupid: 55rwhp at 8K, 110 at 9,200, 152 at 10,600, said to be BANG at 11K. The tape on the alloy pipe cover on the LH fairing side was to give me a bit of cornering wear warning before the track surface went rubbing through the alloy and the pipe, causing seizure (don't ask how I knew to be warned...).

I remember walking around the Barber Museum (all day...and not nearly enough time) and then seeing this bike. At that time, it was kinda tucked away and I remember thinking that it should've been more prominently displayed.

Anyhow, I was able to visit with Brian Slark about the bike. He told me they also have Saarinen's leathers from the '73 Daytona win. He said they looked like a thirteen year boy would have a hard time fitting into them. Jarno was a tiny dude!
